Using a recent result of Busch and Gudder, we reconsider a theorem of Ludwig which allows one to identify a class of effect automorphisms as the symmetry transformations in quantum mechanics.

Neurosteroid 17 beta-estradiol (E2) is a steroid synthesized de novo in the nervous system that might influence neuronal activity and behavior. Nevertheless, the impact of E2 on the functioning of those neural systems in which it is slightly synthesized is less questioned. The vestibulo-ocular reflex (VOR) adaptation, may provide an ideal arena for investigating this issue. Indeed, E2 modulates cerebellar parallel fiber-Purkinje cell synaptic plasticity that underlies encoding of VOR adaptation. Moreover, aromatase expression in the cerebellum of adult rodents is (...) maintained at very low levels and localized to Purkinje cells. The significance of age-related maintenance of low levels of aromatase expression in the cerebellum on behavior, however, has yet to be explored. Our aim in this study was to determine whether E2 synthesis exerts an effective and persistent modulation of VOR adaptation in adult male rats. To answer this question, we investigated the acute effect of blocking E2 synthesis on gain increases and decreases in VOR adaptation using an oral dose (2.5 mg/kg) of the aromatase inhibitor Letrozole in peri-pubertal and post-pubertal male rats. We found that Letrozole acutely impaired gain increases and decreases in VOR adaptation without altering basal ocular-motor performance and that these effects were similar in peri-pubertal and post-pubertal rats. Thus, in adult male rats neurosteroid E2 effectively modulates VOR adaptation in both of the periods studied. These findings imply that the adult cerebellum uses E2 synthesis for modulating motor memory formation and suggest that low and extremely localized E2 production may play a role in adaptive phenomena.

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others. The role of self-projection in time was assessed, in both Experiments, by comparing episodic future thoughts to autobiographical (...) events that were not temporal in nature. Results indicated that episodic future thoughts were more clearly represented than autobiographical future events occurring in unfamiliar setting and future events involving familiar others. Our results also revealed that episodic future thoughts were indistinguishable from autobiographical atemporal events with respect to both subjective and objective detail ratings. These results suggest that future and atemporal events are mentally represented in a similar way. (shrink)

Lack of understanding about the relationship between federal and state educational institutions brings confusion into discussions of democracy, equity and equality in schools. The 'right to education' continues to be espoused by American society as a birthright, yet it does not figure in federal documentation. This matter has repeatedly come to the attention of legislative courts, who have insisted that the question of education as a fundamental right be addressed. Numerous court cases have attempted to bring closure on this issue, (...) on the basis of such abstractions as national rights, equal access, opportunity and economic disparity among the petitions. However, legal judgments remain inconclusive, reiterating that education remains a state legislative issue. This paper explores the implications of a fundamental right to education through an examination of federal and state legal litigation, discussing the philosophical and ideological roots of discussion of rights and democratic values, and evaluating how federal and judicial participation contributes to overall misunderstanding regarding public schooling.

This paper discusses, within the context of analytical theory, some of the implications when rape is subsumed within the international crime of genocide and concludes that this type of enquiry is essential for creating a clearer framework to address and understand this violation. From the analysis undertaken, two critical questions become apparent: a) Does compatibility exist when rape is subsumed within the category of a group violation (genocide), if rape is constructed as a violation of an individual’s sexual autonomy? i (...) b) Is the link between rape and genocide necessarily problematic within this notion of autonomy for the individual victim of rape? The process unfolds within an analytical theoretical approach that touches upon the current concept of human rights with its focus on the individual. Although the key element is the individual, the concept of human rights also creates a space, albeit limited and at times controversial, for the group. As such, this paper identifies some of the theoretical implications that emerge once rape is subsumed within the international crime of genocide, which is defined as a violation committed against particular groups.

ABSTRACTAt present, the consequences and functions of experiences of shame are not yet well understood. Whereas psychology literature typically portrays shame as being bad for social relations, motivating social avoidance and withdrawal, there are recent indications that shame can be reinterpreted as having clear social tendencies in the form of motivating approach and social affiliation. Yet, until now, no research has ever put these alternative interpretations of shame-motivated behaviours directly to the test. The present paper presents such a test by (...) studying the extent to which shame motivates a preference for social withdrawal versus a preference for social approach. Two studies using different shame inductions both showed people experiencing shame to prefer to be together with others over being alone. In addition, the preference for a social situation was found to be unique for shame; it was not found for the closely related emotion of gui... (shrink)

The majority of Dutch physicians feel pressure when dealing with a request for euthanasia or physician-assisted suicide. This study aimed to explore the content of this pressure as experienced by general practitioners. We conducted semistructured in-depth interviews with 15 Dutch GPs, focusing on actual cases. The interviews were transcribed and analysed with use of the framework method. Six categories of pressure GPs experienced in dealing with EAS requests were revealed: emotional blackmail, control and direction by others, doubts about fulfilling the (...) criteria, counterpressure by patient’s relatives, time pressure around referred patients and organisational pressure. We conclude that the pressure can be attributable to the patient–physician relationship and/or the relationship between the physician and the patient’s relative, the inherent complexity of the decision itself and the circumstances under which the decision has to be made. To prevent physicians to cross their personal boundaries in dealing with EAS request all these different sources of pressure will have to be taken into account. (shrink)

Past research has identified a number of asymmetries based on moral judgments. Beliefs about what a person values, whether a person is happy, whether a person has shown weakness of will, and whether a person deserves praise or blame seem to depend critically on whether participants themselves find the agent's behavior to be morally good or bad. To date, however, the origins of these asymmetries remain unknown. The present studies examine whether beliefs about an agent's “true self” explain these observed (...) asymmetries based on moral judgment. Using the identical materials from previous studies in this area, a series of five experiments indicate that people show a general tendency to conclude that deep inside every individual there is a “true self” calling him or her to behave in ways that are morally virtuous. In turn, this belief causes people to hold different intuitions about what the agent values, whether the agent is happy, whether he or she has shown weakness of will, and whether he or she deserves praise or blame. These results not only help to answer important questions about how people attribute various mental states to others; they also contribute to important theoretical debates regarding how moral values may shape our beliefs about phenomena that, on the surface, appear to be decidedly non-moral in nature.
